Drip tip O ring size

[Leithan]

The O ring disintegrated on a very nice SS pawn drip tip. Any one know what the size of the O rings used on most 510 drips is?

Should be a #47. Home depot has them

awesome, just what I needed, didn't want to buy a bunch of sizes till I found the right one, my home depot only sells them in like a bag of 10. Would of gotten expensive quick.
